How to set NeoVim as external script editor on macOS in 2022?

As title. I have tried many ways on the Internet and read many threads on this forum. The most promising post is this one: https://forum.unity.com/threads/unity3d-with-vim.355814/#post-7892389 (linked to my reply), in short, the picture describing my problem is the same as this reply on the same thread: https://forum.unity.com/threads/unity3d-with-vim.355814/#post-3420892

The other answers are too old and cannot be applied nowadays.

I'm using macOS 12.2. I build neovim from the source. I tried following this tutorial, Configure (Neo)Vim for Unity Game Engine Development (chrislabarge.com), to create a script that should be selectable when I hit "Browse...", but the script dimmed out so I stuck.

 

I resolved this myself. Boring forum

 

Hey, can you share what you did to resolve this?

 

It's rare one comes across another wanting to use nvim for unity. You should at least write down what you did to get it accomplished
